Abstract – Harvesting energy through road is an approach for generating power by using Green Technologies. These green technologies include: thermo-electric generator with piping system, piezo-electric method & photovoltaic noise barrier system. The main objective is to reduce the carbon emissions & protect the environment. This report documents the theoretical study of the above mentioned three systems for a certain length of road. The study extends from basic principle to the payback period calculation of each green technologies. Key Words: Green energy, thermoelectric generator, piezoelectric material, P.V sound barriers, harvesting energy. 1. INTRODUCTION
“Investing in green technology is an investment done for our future”
facilities for electricity and for heating of water during winter time. DESIGN FOR 5 KM OF HIGHWAY Hot water storage tank It involves storing water in it which further supplied heat to the semiconductor which is used to convert it into to electricity. The material of this tank selected is copper along with anti-oxidant layer in order to prevent corrosion -Thermal conductivity = 385 watt/mk This water tank build is insulated in order to prevent the liberation of heat from the water tank which also help to maintain constant temperature at hot side. The material used for insulation of hot side of TEG is ceramic
Investing in green technologies is beneficial because of the fact that conventional sources of fuel is limited to generations. Green technology helps to achieve sustainability in energy management. Thermo-electric generator with piping system works on the heat absorbed by the pavements. The piezo-electric system works on the principle of generating electricity by converting vibrations created by vehicles to electricity, while PVNB system rests its base on harnessing power from sunlight for generating electricity.
-High insulation capacity [It can insulate heat up to 18000 c].
2. PROBLEM DEFINITION
It basically consist of the pipes that are arranged in zigzag pattern.
Large amount of electricity is consumed by street lights, hoarding and other loads at high cost generated through conventional means. This conventional means also create pollution while producing electricity.
Pump The water is to be pumped through pipeline which is circulated in the close loop from pipes to the water tank. -Flow rate = 500 to 2000 litre/hour Copper pipe
For flow rate of 20 litre/min Inside diameter of pipe is given by D =√Qw /3600v x 4 /π
Total Street light transmission cost/day = Rs. 89, 39,204.25
Velocity = 0.2 m/s
Total cost of electricity/day= 19, 89, 39,336 Rs.
Pipe inside diameter = 46.07 mm
Thermoelectric generator with piping system
Heat transfer through pavement
Green energy harvesting aims to supply electricity to street light systems from one or different energy sources present in the environment without grid connection. These energy sources is thermal energy (thermoelectricity). The thermoelectric energy harvesting technology converted into electrical energy. This system works on seebeck effect, the electricity generated is directly proportional to the temperature difference of hot side and cold side. The daily working time of this system is around 6 to 7 hour per day. The stored energy could then be used for supporting nearby © 2020, IRJET
